"Webmachine type is now defined in the device tree itself. The bootloader can dynamically add some information (for example, clock frequencies) to the device tree and then passes a pointer to the tree, located in system memory, through r2 (for ARM® architecture) or r3 (for Power Architecture®). The kernel then unflattens and parses the device tree. " - Hackinton stop io devices tree
